Venezuela-Trinidad Crustal and Mantle Structure: A Collaborative Broad Band Seismic Experiment

这项研究将在委内瑞拉东北部和特立尼达安装和运行REFTEK/STS-2地震系统的五站便携式宽带阵列，为期一年。目标是对东加勒比-南美洲板块边界的地壳和上地幔结构进行成像。该项目是委内瑞拉因特韦普地震学小组、特立尼达地震研究单位的科学家和卡内基研究所共同努力的成果。地震实验的目的是回答有关孕震板块边界性质的悬而未决和有争议的问题。地震分析将集中在两个广泛的领域：1)委内瑞拉下方残留板的地震证据的存在或不存在；2)通过分析边界相互作用阶段、面波反演以及延迟时间和旅行时间的测量来确定地壳和上地幔结构。这项研究是国家减少地震灾害计划的一部分。

This research is to install and operate for one year a five- station portable broadband array of REFTEK/STS-2 seismic systems in northeastern Venezuela and Trinidad. The goal is to image crustal and upper mantle structures of the eastern Caribbean-South America plate boundary. The project is a collaborative effort between the seismology group at INTEVEP, S.A. (Venezuela), scientists at the Seismic Research Unit, Trinidad, and Carnegie Institution. The purpose of the seismic experiment is to answer outstanding and controversial questions regarding the nature of the seismogenic plate boundary. Seismic analysis will focus on two broad areas: 1) the presence or absence of seismic evidence for a relict slab beneath Venezuela and 2) determination of crustal and upper mantle structure by analysis of boundary interaction phases, surface wave inversion, and measurement of delay times and travel- times. This research is a component of the National Earthquake Hazard Reduction Program.
